But things are back to normal as they move into Windermere Manor... until the sisters climb a strange ladder in a fireplace and enter the magical land of Arden. There, they find a world in turmoil. The four guilds of magic no longer trust each other. The beloved unicorns have gone, and terrible wraiths roam freely. Scared, the girls return home. But when Sophie vanishes, it will take all of Claire's courage to climb back up the ladder, find her sister, and uncover the unicorns' greatest secret.

And now, Elsa will be setting sail for a grand tour of the world--leaving Anna behind. But a mysterious sickness strikes Arendelle, and Elsa's tour is delayed, giving Anna the perfect opportunity to finally help. When Anna discovers a secret room in the castle and incants a magic spell, she hopes it will make her dream of curing the sickness come true. Instead, a more sinister dream comes to life.
